This molybdenum wire evaporation material requires e-beam evaporation as the preferred deposition method, with thermal evaporation only permissible for thin charges under qualified setups. Deposition source hardware must be water-cooled e-beam hearth or tungsten/tantalum support by RFQ, and process parameters must account for the material's melting point of 2,617°C and Z-ratio of 0.257 for accurate thickness monitoring.
- Deposition Method Compatibility: E-beam evaporation is the preferred method; thermal evaporation is only acceptable for thin charges with a qualified setup.
- Source Hardware Requirement: Use a water-cooled e-beam hearth or tungsten/tantalum support by RFQ for evaporation.
- Melting Point Consideration: The high melting point of 2,617°C requires sufficient source power and thermal management to avoid damage.
- Z-Ratio Calibration: The Z-ratio of 0.257 must be entered into the thickness monitor for accurate film thickness control.
- Pre-Order Confirmation: Confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before quotation.
Why is e-beam evaporation preferred over thermal evaporation for this molybdenum wire, and what qualifies as a 'qualified setup' for thermal use?
E-beam evaporation is preferred because molybdenum has a high melting point of 2,617°C, making thermal evaporation challenging without specialized hardware. Thermal evaporation is only recommended for thin charges or qualified setups, which typically involve using a water-cooled e-beam hearth or tungsten/tantalum support configured via RFQ to handle the high temperature without contamination.
What evaporation source hardware is compatible with this Mo wire, and when is an RFQ required?
The molybdenum wire is compatible with a water-cooled e-beam hearth for direct evaporation. For thermal evaporation using tungsten or tantalum support boats or filaments, an RFQ (request for quotation) is required to confirm the specific hardware configuration and ensure proper handling of the high melting point material.
How should the Z-Ratio of 0.257 be applied when using this molybdenum wire with a quartz crystal microbalance for film thickness monitoring?
The Z-Ratio of 0.257 must be entered into the deposition controller's quartz crystal monitor (QCM) tooling factor to correct for the acoustic impedance mismatch between molybdenum and the quartz crystal. This ensures accurate real‑time thickness measurement during e‑beam or thermal evaporation of this 99.99% pure Mo wire.
This Molybdenum evaporation wire (99.99%, 1.0 mm dia.) is suited for e-beam evaporation but requires careful source geometry matching and is not recommended for standard thermal evaporation processes without prior qualification.
Positive
- High Purity (99.99%): The 99.99% purity specification enables consistent film quality and supports comparison with standard, high-purity, or RFQ-controlled grades for contamination-sensitive applications.
- Wire Form with Defined Diameter: The wire form with 1.0 mm diameter facilitates predictable source loading and evaporation review, aiding process reproducibility in e-beam evaporation systems.
Trade-offs
- E-Beam Preferred, Thermal Limited: E-beam evaporation is the preferred method; thermal evaporation is only recommended for thin charges or qualified setups, restricting process flexibility for standard thermal systems.
- Pre-Purchase Compatibility Verification Required: Buyers must confirm deposition source geometry, pack size, certificate requirements, and shipment conditions before quotation, adding an engineering review step to procurement.
